Editing Miamisburg, Ohio (section)

==History==
European-Americans started calling their first community "Hole's Station" ''circa'' 1797, when Zechariah Hole settled there with his family from [[Virginia]] and built a stockade on the west bank of the [[Great Miami River|Miami River]] opposite the mouth of Bear Creek. The stockade attracted squatters, surveying parties, and other settlers who had taken grants to live in the local cabins until they could build their own; hence the little community became known as "Hole's Station". Settlers came west primarily from [[Pennsylvania]]. Miamisburg was incorporated in 1832 as a village; it achieved city status in the 1920s.<ref name=history>{{cite web |title=History |url=https://cityofmiamisburg.com/about/#:~:text=The%20name%20Miamisburg%20was%20derived,status%20about%20100%20years%20later. |access-date=March 13, 2023 |website=CityofMiamisburg.com |publisher=City of Miamisburg}}</ref>

By 1827, the [[Miami and Erie Canal]] was under construction through the community, which improved transportation of people and goods through the region. The formal opening took place in January 1829, when the ''Governor Brown'' was the first [[packet boat]] to go through the settlement. Also that year the first boats from [[Cincinnati]] had arrived and passed through Miamisburg to get to Dayton. By 1834 the canal had been extended to Piqua, and many businesses along the river grew. The 1840s and the 1850s were brought the best of times to the canals.{{citation needed|date=June 2016}}

Miamisburg was the site of one of the first post-war U.S. [[United States Atomic Energy Commission|Atomic Energy Commission]] (AEC) facilities, beginning in 1947. The Dayton area had supported numerous [[Dayton Project|secret operations]] for the War Department during [[World War II]]. As the war ended, the majority of these operations were moved to the Miamisburg [[Mound Laboratories|Mound Laboratory]], which was operated by the [[Monsanto Chemical Company]]. The Mound Labs were to monitor all aspects of the US nuclear defense stockpile.{{citation needed|date=June 2016}}

The Mound Plant, built in 1947, was situated on a {{convert|306|acre|adj=on}} site in the city {{convert|10|mi|km}} south of Dayton. The workers, who numbered more than 2,000 at the height of the production, made [[plutonium]] detonators for [[nuclear weapons]]. Their work was very classified. The plant had a small army of security guards and was ringed by chain-link fencing and razor wire. When the [[Cold War]] ended, the plant discontinued the detonator work, but it continued to make nuclear power generators for space probes.{{citation needed|date=June 2016}}

In May 1993 [[U.S. Department of Energy]] decided to end all production at the Mound. This move affected 2,100 employees in the local area. By 1996 cleanup of radioactive and hazardous waste was the main activity at the Plant. The Mound Development Corporation spearheaded the creation of the Mound Advanced Technology Center in the redevelopment of the plant, with the Montgomery County Regional Dispatch Center joining 14 other tenants in March 2009. In December 2010, the Dayton Police Department became the 17th law enforcement agency, along with 11 fire departments, to be dispatched from the regional center.{{citation needed|date=June 2016}}

Eight years later the city was the site of the [[1986 Miamisburg train derailment|July 8, 1986 derailment]] of 15 cars of a [[Baltimore and Ohio Railroad]] train, resulting in explosions of tank cars, emitted gas and clouds from phosphorus, on two successive days. The resulting thick white cloud engulfed communities as far north as Yellow Springs, Pitchin, and South Vienna.  Rolling in like a massive desert dust storm across the horizon, the chemical cloud hugged the ground and blotted out the sun for several minutes before dissipating, according to the [[National Transportation Safety Board]]’s report. The explosions led to the evacuation of an estimated 25,000 to 40,000 residents from Miamisburg and surrounding southern Montgomery County municipalities, at the time this was the largest evacuation in U.S. history resulting from a train accident, according to William E. Loftus, executive director of the [[Federal Railroad Administration]]. This was also the largest evacuation in Ohio history.<ref>{{cite web|archive-url=https://web.archive.org/web/20230223001709/https://apnews.com/article/3b01cc098e6e468bab0c64344571918b|first=Doug|last=Fisher|work=Associated Press|date=1986-07-10|title=Fire Continues to Smolder; Most Evacuees Return Home|url=https://apnews.com/article/3b01cc098e6e468bab0c64344571918b|archive-date=2023-02-23|access-date=2023-08-05}}</ref><ref>{{Cite web |date=2022-05-17 |title=Timeline: 1986 fiery train derailment in Miamisburg |url=https://www.wdtn.com/news/local-news/timeline-1986-fiery-train-derailment-in-miamisburg/ |access-date=2023-06-21 |website=WDTN.com |language=en-US}}</ref><ref>{{Cite book |url=http://archive.org/details/hazardousmateria03netc |title=Hazardous materials release following the derailment of Baltimore and Ohio Railroad Company train no.
